Morphology | Morphometrics
soft rays: 5. Submarginal black band on inner pectoral fin surface complete; eyes relatively large; snout relatively short; hump on back less obvious as in S. diabolus; SL to 10.4 cm. No black spot nearly as large as eye on inner surface of pectoral fins. A narrow triangular black mark inside mouth at front of upper jaw behind teeth. Ascending process of premaxilla broad, its maximum width 1.4-1.8 in orbit diameter. No series papillae or nodules across interorbital space between supraocular spines. Nasal spine single (Ref 42181).
A rare inhabitant of mixed sand and rubble areas of reef flats and shallow lagoons. Feeds on fishes (Ref. 89972). Usually buries itself in the substrate when in sand or sits amongst rubble where it has good camouflage (Ref. 48635). Anterolateral glandular grooves with venom gland (Ref. 57406). Solitary or in pairs (Ref 90102).
